Design of an Axial Fan Using ANSYS Turbo System
Meanline Design
Welcome to our discussion on turbo machinery. In this session, we will focus on designing and analyzing an axial fan from scratch using the ANSYS Turbo System.
Starting the Design Process
- Open the ANSYS workbench.
- Navigate to Component Systems and double-click on Vista AFD (Axial Fan Design).
- Click on the Mainline button to open a new window.
Defining Design Operating Conditions
In the new window, we will define our design operating conditions at the best efficiency point:
- Working Fluid: Air
- Parameters: Rotational speed, pressure drop, and mass flow rate
Note: We will not model the inlet guideway or the outlet guideway, focusing instead on the flow rate.
Calculating Initial Estimates
Click the Calculate button to obtain quick estimates on the performance of our meanline design. The table will display:
- Power
- Torque
- System Efficiency
- Other key parameters for a turbo machine
Analyzing the Meanline Design
- Close the initial window.
- Proceed to the next step by hitting the Calculate button to invoke the true flow solver.
- Add a new function for a more detailed and accurate analysis of fan performance, including power and system efficiency.
We do not see any red or tagged numbers, indicating that the design is sufficient in terms of performance.
Conclusion
At this time, we are ready to move on to the next step of our design process.
Title: Design of an Axial Fan using ANSYS TurboSystem - Meanline Design Hello, let's talk about turbo machinery. Specifically, let's discuss designing and analyzing an axial fan from scratch using ANSYS Turbo System. Let's start by opening our workbench in ANSYS.
Go to Component Systems and double click on Vista AFD. Here, AFD stands for axial fan design. Let's start our design by clicking on the mainline button, which will bring up a new window. On this window, we're going to define our best efficiency point or our design operating conditions.
This will use air as the working fluid, and we've defined rotational speed, pressure drop, and mass flow rate. We do not want to model the inlet guideway or the outlet guideway. We're going to concentrate on the flow rate.
We're going to use the same settings, and then I'm going to hit the calculate button. This will do some quick estimates on the performance of our meanline design. Here in the table, we can see the power, torque, system efficiency, and some other key parameters for a turbo machine.
Let's close this window and move on to our next step, where we're going to analyze this meanline design by hitting the calculate button here. This will invoke the true flow solver that is available.
We're going to add a new function called "Performance," which will provide a more detailed, accurate analysis. This will output results for our fan performance, such as power, system efficiency, and others. We do not see any numbers in red or tagged, which is good news.
This means the tool is not warning us that the design may not be sufficient for performance. At this time, we're ready to move on to the next step of our design.
